What an angel this man is. He put a cast on his arm in order to prove to a fellow gastroenterologist that he will be able to do scopes even though 95% of his function had been lost after being wounded in the 2017 shooting. " The purpose of the cast is not to help him regain control of his hand. In fact, it is to restrict his wrist movement to 95 percent of its normal function, which is what Dr. Hassan Tariq, who was one of the six people wounded in the shooting, is expected to regain after he recovers from surgery. Dr. Tariq and Dr. Chilimuri both specialize in gastroenterology, a field that requires finesse in both hands. Dr. Chilimuri has told Dr. Tariq that he will be able to return to work, but Dr. Tariq remains anxious. So Dr. Chilimuri wants to prove to him that he will be able to perform the duties for which he has trained the past six years."
